A fluorine-containing copolymer composition comprises a fluorine-containing copolymer, comprising a fluoro-olefin and an organic silicon compound having an olefinic unsaturated bond and a hydrolyzable group, and an organic silicon compound having an isocyanate group. This composition is soluble in an organic solvent at normal temperature and is curable at normal temperature. If a curing catalyst is incorporated in the composition it can be used as a coating composition.
